Instance Property


The damping ratio that limits oscillation in the vehicle’s suspension.


var suspensionDamping: CGFloat { get set }


Damping ratio measures the tendency of the suspension to oscillate after a shock—in other words, for the vehicle to bounce up and down after running over a bump. The default damping ratio of 2.3 causes the wheel to return to its neutral position quickly after a shock. Values lower than 1.0 result in more oscillation.
